✦ Synopsis

The maximum temperature for growth of a strain of Kluyv~ro,r~ces fragilis was depressed by increasin=~ ethanol concentration fro~ its normal value around 45°C to 26.5 C at 6.4% (w/v) of ethanol. Ethanol enhanced thermal death by increasing AS~, the entropy of activation of thermal death. Entropy ooefficients of 7.6 entropy units per col of ethanol per liter of medium for unadapted cells and of 5.7 for adapted cells were obtained.
